Oscillators
DeMarker
An oscillator between 0 and 1 that compares recent highs and lows to spot exhausted moves.
L’idée en termes simples
If each candle keeps making higher highs, buyers are in control; if lower lows, sellers are. DeMarker measures the balance of these pushes over the last few candles.
Mode de calcul
Each candle, DeMax is how much the high rose versus the previous high (0 if it did not), DeMin how much the low fell. The indicator is the average DeMax divided by the sum of both averages.
DeMax = high − previous high if positive, else 0
DeMin = previous low − low if positive, else 0
DeMarker = SMA(DeMax, N) ÷ (SMA(DeMax, N) + SMA(DeMin, N)) (default N = 14)Comment l’utiliser
- Above 0.7: the move up may be exhausted. Below 0.3: the move down may be exhausted.
- Works best for timing entries in the direction of a bigger trend (buy dips below 0.3 in an uptrend).
Tirer des conclusions
- Turning back from an extreme is more useful than simply being there.
Exemple
In a rising market, DeMarker dips to 0.25 during a pullback and turns up: a buy-the-dip signal in line with the trend.

Points de vigilance
- Extremes can persist in strong trends.
